R Nine One from Rocket Espresso is designed by the Italian engineer Ennio Berti who aimed to achieve even more precise temperature stability so that every espresso would be perfect. With water-filled brewing groups to promote temperature stability through PID controlled electronics in boilers made entirely of stainless steel, one can certainly say that he succeeded.
Note that when selecting wood options, an incorrect product image is shown. We only sell R NINE ONE with stainless steel side panels with the option of a standard plastic handle set or the four different wood options.

R Nine One is made for the professional home barista as well as for smaller establishments that want to serve really good coffee. Ergonomically well-designed steam wand with two holes provides really strong pressure on the steam. The milk is ready within seconds just like on espresso machines for commercial use.
Rocket Espresso R Nine One is a well-designed professional espresso machine that looks really stylish both in a small café and at home in the kitchen. This machine has a unique design and capacity for its size. The espresso machine has a built-in water tank but can also be connected to water and drainage.
The perhaps foremost specification that makes R Nine One an exceptional espresso machine is the brewing profiles. The ability to customize 5 unique brewing profiles allows for experimentation with almost everything for a long time. Within its brewing profiles, you can set 5 different parameters, meaning you can set 5 different pressure and time settings in the same brew. Thus, About if one wanted to imitate a lever machine (an espresso machine where pressure is manually created by pulling down a vertical lever), one could program a profile so that for example in (1) 5 seconds run 12 bar, (2) 6 seconds run 11 bar, (3) 4 seconds run 10 bar, (4) 4 seconds run 9 bar and finish with running (5) 8 bar for 6 seconds. Here you have thus chosen to change the pressure and time 5 times, which is the maximum number. The pressure can be set between 0.1–12 bar. Nowadays, it is common to want to do a so-called pre-infusion which means soaking the coffee a little before starting the actual brewing. Some claim that this makes a significant difference while others argue that it is hardly noticeable. Why not create two different profiles, one using pre-infusion and the other brewing in the traditional way? Experiment yourself and find your own answer.
All these settings can be easily found in the digital display on Rocket Espresso R Nine One. Page 2 of the menu shows a graph symbol in the bottom right corner, click on this to change the profiles. The left column indicates time and the right indicates pressure. Please read the accompanying manual to see exactly how everything is set up.
Once you have set up your profile and brewing, a graph on the digital display will continuously show the pressure and time. For the crazy coffee lover, this is an exciting experience that allows for absolute perfection. Just look at the curve and assess About if anything could be improved for next time. Not only does it look cool, it also helps quite a bit.
Rocket Espresso R Nine One is equipped with a water-filled brewing group which essentially means that the flow between the group and the boiler is continuous. This means that the temperature is always the same, resulting in incredibly consistent cup-to-cup results. R Nine One is also equipped with a volumetric permanent magnet pump. This means a quieter, more stable brewing of your espresso.
Not only can you make really great coffee with the R Nine One, it is also very practical with its programmable on-off function. Within a 24-hour span, you can set it to turn off and on 2 times. This means that the coffee machine can be ready for use when you get up in the morning and are in dire need of coffee. Then it turns off just in time for you to go to work and can be turned on again so that the evening's coffee after dinner is also excellent. And during the night it is turned off to save energy and thus the environment.
The new steam system is equipped with a pressure sensor that makes a big difference for the barista who wants to produce many perfect cups in a row. The previous NTC temperature sensor that earlier models have worked with means that when the barista opens the steam, it takes up to 15 seconds for a noticeable difference in temperature to be detected by the sensor. Once it detects a difference, it signals the system to turn on the element to maintain the heat in the boiler and thereby the pressure. This means that a certain uneven pressure can occur due to the delay. The new pressure sensor sends a signal About pressure change immediately when the barista opens the steam. At this moment, the sensor ensures that the system is aware of this and turns on the element immediately. This makes the steam pressure smoother than ever, and the hard-working barista never has to worry about a certain difference occurring. In short, the older one is a temperature sensor, and the new one is a pressure sensor which increases temperature stability when frothing milk.
Accompanying the R Nine One is a single handle, a double handle, a naked filter handle, a tamper, a cleaning brush, a blind filter, and a water connection hose.
